PROCESS FOR PRODUCTNG A PREPARATION FOR SOFTENING AND OILING TEXTILE FIBERS. v I

No Drawing. Application filed March 24, 1927., Serial No. 178,139, and in Germany March 27, 1926.

The present inventiog relates to the manufacture of a softeningand oiling preparation to be used in the spinning of textile fibers. I p I Softening and oiling preparations to be used in the spinning of textile fibers are generally produced by emulsifying olein and water with an alkali, ammonia or'sodium carbonate added thereto, whereby the olein becomes partly saponified.

Now' I have found that in the manufacture of softening and oiling preparations for use in spinning there may be obtained emulsions of an extraordinary stability by simultaneously adding to the mixture of an oil and Water alkylated cellulose and sulfonic acids or water-soluble salts of such aromatic or hydratedaromatio sulfonic acids as contain as side chain hydrocarbon residues such .20 as the alkyl-, aryl-, aralkyl-, or cycloalkyl residue, either alone or mixed one with another .The oiling preparation thus producedposseissesabove all the advantage that it has not "only an excellent emulsifying power, butalso a great wetting power, which ensures a rapid and uniform impregnation of the wool fibers with the softening liquid. Fu i'thelmore, the oiling preparation thus obtained has no tendency to gelatinize, a fact which is of the-highest importance for'its practical use.

The oiling preparation may be produced with or without the addition of an alkali. The woo} fiber is preferably moistened by means of one of the usual spraying devices.

The following example serves to illustrate my invention, but is not intended to limit it thereto, the parts being parts by weight.

300 parts of water are mixed with an aque-v ous solution of 2, 5 parts of dimethyl cellulose and 2, 5 parts of sodium isopropylnaphthalenesulfonate. Into this mixture are run, while continuously stirring, 80 parts of olein, until the latter forms an entirely homogeneous emulsion. The'oiling preparation so obtained is then applied in the usual H manner.

:Instead of sodium isopropylnaphthalene- {.suljfonate there ma also be used for instance sodium dibutylnapiithalenesulfonate,- sodium tion for softening an benzylnaphthalenesulfonate, butylnaphthaleiie sulfonic acid, whereas instead of olein there may be used olive oil, a. mineral oil or the like, or mixturesof'these oils.
